Thanks for the visual and negativity.
I estimate I can wrap my house in 3 to 4 inches of spray foam for $7000, and get double the r value of what I can fit with cellulose in the space available. I have to air seal anyway. I am working one room at a time and one 600 sf kit does one room perfectly. it just works for me.
